2004 Safari Panther travel mode ride height.

My recently purchased coach is on a Roadmaster S chassis with a tag. The manual says height measurements on bags should be 9" front and rear. The current measurement of the front bags on the rear axle is at 10" and the rear bags seem to be about 2" shorter.Aall bags on the front are at 9". The whole coach appears to be too high. The front of the coach appears to be about 1" higher than the rear if measured off of a level line on the body.
I got under it today and tried to lower the ride height with the leveling valves using the method described in the manual of loosening the arm from the lever. I bottomed out the adjustment in the slot and was still about 1/2" too high at the rear. The only other way to adjust it down would be to shorten the rod. This situation seems odd to me unless a previous owner installed longer rods trying to increase ride height. I haven't done anything with the front yet and looking for a reality check on what I've found so far.

Any help would be greatly appreciated .

Are you lowering bags air then returning to travel, move coach a mile or so then re check?

I have not. I was following the instructions in the Safari owners manual. It didn't mention that, but I'll have to give it a try.

Well, Big surprise for me today. I found that my odd measurements were a result of the dreaded cracked vertical trailing arm issue. Mine are completely broken on both sides and look to have been broken for quite some time. I thought that this was an issue only with the RR8 and RR10 chassis so wasn't even looking for it on my RRS. Also found the front two shocks had broken off the upper mounting studs and we pushing into the floor. Once I pulled them off I found that the upper eyes were elongated like the shock had been repeatedly pulled into full extension. I realized after finding the break that the vertical trailing arms are not actually vertical right now which is inducing a roll in the axle tube and throwing the H frame out of level. Thus the difference in measurement of the height of the front and rear bags on the same axle. I didn't know that they were the same bags and should all be about the same height. Remember I haven't owned this coach for even a month yet, so I'm learning a lot in a hurry. Anyway, now onto the fix. There are plenty of good threads covering repairs and Monaco's gusset upgrade to the 2008 and newer units. I'm planning to get started tomorrow.

Here's what it looks like.

First one is passenger side, second is driver's.

Only 55,000 miles on this unit. Looks like it has been this way for 10,000 miles, the way the passenger side is worn.

Thanks, Mike. Seeing how others have done it makes me feel more confident. Almost took it to a shop this morning, but I hate wondering about how good of a job they will do.

Yeah, like you, I'd rather do it myself to ensure the welds are burned in good and the repair is done properly.

Those are really fixable. Crazy how they broke like that though. Must be some serious forces being applied there. Thanks for sharing pics!

Thanks for the pictures, gives me more place to look for problems.


I do almost all my own maintenance and have recently crawled under my rig front to back. I always look at the welds on the vertical supports on the axle itself as this is where there have been multiple failures.



Now I just have to look up.



But I don't weld, wish I could but never learned and something like this you need someone than knows what their doing. Hopefully I won't have to look for someone.



Good luck on the repair!

I recently had this repair done and it took a lot of phone calls before I found someone willing (not just able) to do it. Many didnít want to take on the liability. But I finally called a big rig shop who did it without hesitation. This shop routinely cut and either lengthened or shortened big rig trailer frames and did a perfect job. Pretty reasonable too. Good luck. It is very fixable.

And, likely an old-time (i.e. OLD) welder can weld in a plate to sister/reinforce the broken areas.


Were it mine, that is exactly what I would do. Look for a welder with over 40 years experience to repair (vs new guys who would say replace).

For mine they ended up fixing the break with a v-joint, they also inserted a solid steel bar into the tube, drilled four holes into the tube and welded the steel bar to the tube through the holes. They finished it off with a 3/8" gusset along the rear of the tube.
